We offer several varieties of meter relays and digital indicators for measuring, monitoring and controlling any electrical or process parameter. Meter relays are ideal for process control and load shedding applications, combining an indicator with set points which trigger alarm and control circuits when the signal deviates from set limits. This range includes digital and analog meter relays, digital bargraph indicators and controllers. Instruments are designed for control panels and switchboards, monitoring systems, power generation and control applications.
